SPECIFICATION forming part of Letters Patent No. 777,048, dated December6, 1904.

Application lefl February 25, 1902.

Be it known that I, ROBERT i/V. SCOTT, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Ribbed Knitted Fabrics, of

which the following is a specification.

My invention consists of a ribbed knitted fabric having' a looped orpile surface capable of being iieeced or brushed, the loops which IOform said pile-surface being' formed by one of the strands of acomposite knitting-yarn and not, as heretofore, from a supplementaryyarn engaging' with the wales formed by said main knitting yarn oryarns.

I5 Heretofore plain knitfabricshavebeenprovided with a pile surface byforming loops from one of the strands of a composite main knitting-yarn;but fabrics of this character are comparatively inelastic, andconsequently 2O their range of usefulness is quite limited.

vWhen in knitting a plain fabric an elongated loop is cast off of aheddle of the machine, together with the loop of ordinary length, bothof the loops will be thrown to 2 5 the back of the fabric; but inknitting a ribbed fabric the simple elongation of the loop of one strandof the composite knitting-yarn would result in the casting of saidelongated loop between the front and back wales of the fabric, so thatit could not be acted upon by the brush used to form the licece. Incarrying ont my invention, therefore, l project one or more of thestrands of the composite knitting-yarn between the wales of that face ofthe fabric selected for the pile-surface, .so as to form loops extendingbeyond said wales, whereby said loops can be brushed without injury tothe body-wales of the fabric.

In producing' my improved fabric I use a 40 machine having' loopers orsinkers so arranged that they can act upon one of the strands of thecomposite knitting-yarn without acting upon the other strand or strandsof the same.

The figures in the accompanying drawings represent, on an exaggeratedscale, pieces of ribbed knittedV fabric and illustrate various methodsof carrying out my invention in the production of such fabric.

In the drawings, l, 2, 3, 4, and so on rep- Serial No. 95,506. (Nospecimens.)

resent successive courses of the fabric. a and 7) represent adjoining'needle-wales of the same, and c the sinker-wales, the stitches in theneedle-wales a being' drawn in one direction or to one face of thefabric, the stitches in the needle-wales being drawn in the oppo- 55site direction or to the other face of the fabric, and the yarn in thesinker-wales extending. from wales of one face of the fabric to wales ofthe other face, as is usual in ribbed knitted fabric. The knitting-yarnemployed, 6C however, is a composite yarn having' in the fabric showninFigure l two strands a' and m', these strands being controlled byindependent yarn-guides or one guide with two feedholes, so that onestrand can be acted upon independently of the other. In course l of thefabric the strand ir' is projected from the composite yarn where thesame forms sinker-wales c, so as to forni loops y, which projectoutwardly beyond the wales b in order that they can be readily brushedwithout injury to the knittingyarn constituting the said wales, theseloops being formed by applyingI the strand a" of the knitting-yarn to aprojecting looper or sinker in its course from the needle which producesthe wale to the needle which produces the wale a. ln course a the strandm of the knitting-yarn is projected so as to forni loops y/ on theopposite face of the fabric from that on which the SO loops 1/ areformed, the operation being the same except that the leopers or sinkcrsdraw the loop in the opposite direction from those which formed theloops z/. In course 6 I have illustrated the formation of loops on bothfaces of the fabric, and in course 8 l have shown the loops jl/ as beingformed from the strand zu of the knitting-yarn; but this strand does notform stitches in the wales of the fabric, the yarn-guides in this casebeing so arranged that the guide which controls the strand ,fr will feedthe same to both sets of needles; but the guide which controls thestrand ai will feed the same only to the needles which produce the walesa and to the sinkers or loopers, this strand passing behind or ont ofthe path of the other set of needles, which produce the wales L. Incourse 1l I have shown the strand a" of the knitting-yarn as formingloops y without forming stitches in the wales a of the fabric. Theyarn-guide controlling strand in this case feeds said yarn to theneedles which form the wales and to the sinkers or loopers, but layssaid strand ze behind or out of the path of the needles which form thewales a.

A composite knitting-yarn otherwise disposed, as in courses 8 or l1, maybe caused to form loops on both faces of the fabric by subjecting itsstrand a to the action of loopers disposed in every one of the spacesbetween the needles instead of only in every other space.

In course l, Fig. 2, I have shown an arrangement of the strands verysimilar to that shown in course 8, except that the loops y2 overlapwales b instead of being drawn out between the wales t and and in course3 is shown a similar fabric, in which, however, each composite yarn iscomposed of three strands m rc2 instead of two strands, the strand m2being the one which forms the loops.

In course 6, Fig. 2, I have shown various means of carrying' out myinvention by simply elongating one of the strands of the composite yarnin the formation of the stitch, this strand being drawn into a longerloop g/S than the other strand of the yarn in the formation of thestitch. This form of loop can be produced by employing two needles sideby side, one capable of greater draft than the other, each needlereceiving its respective strand of yarn in forming the course in whichthe elongated loops are to be drawn, one needle drawing a longer loopthan the other and both needles receiving the composite yarn and havingthe same extent of draft in forming the next course. l F or greaterclearness of illustration I have shown in the drawings the employment ofthe multiple-strand knitting-yarn only in those courses of the fabric inwhich the fieecingloops are formed, although in practice themultiple-strand knitting-yarn will usually be employed in every coursein order to produce a uniform fabric.

It is to be understood that although I have shown the invention asapplied to the production of a plain-ribbed fabric, it is clearlyapplicable to the production of knitted fabrics in tuck-stitch, thelocation and disposition of the fleecing-loops in the latter case notvarying materially from those shown in the drawings.

Having thus described my invention, I claim and desire to secure byLetters Patent-- 1. A ribbed knitted fabric having loops formed from amultiplicity of strands, some of said strands being looped longer thanthe others, and said elongated loops projecting beyond the wales of eachface of the fabric, substantially as specied.

2. A ribbed knitted fabric having loops of either face formed from amultiplicity of intermeshed strands, some of said strands beingprojected from the sinker-wales of said face of the fabric to form loopsprojecting beyond the needle-wales of said face and overlapping thebacks of the needle-wales of the other face of the fabric, substantiallyas specified.

3. A ribbed knitted fabric having loops formed from a multiplicity ofstrands, some of said strands being projected from the sinker-wales ofthe fabric so as to form on each face of the fabric loops projectingbeyond the wales of said face, substantially as specified.

4. A ribbed knitted fabric having loops formed from a multiplicity ofstrands, some of said strands forming loops in both sets of needle-walesof a course, and the other strand or strands forming loops in but oneset of needle-wales of the course, and being projected between the fullstrand-wales so as to form loops extending beyond the wales of eitherface of the fabric, substantially as specified.

5. A ribbed knitted fabric having loops formed from a multiplicity ofstrands, some of said strands forming loops in both sets of needle-walesof a course, and the other strand or strands forming loops in but oneset of needle-wales of the course, and being projected between thefull-strand wales so as to form loops extending beyond the wales of eachface
